A NAS A spacecraft that will deliberately crash into an asteroid (小行星) is preparing to launch this week. The DART mission, or the Double Asteroid Redirection Test, will lift off at 10:20 p. m. PT on November 23, 2021 aboard a Space X Falcon 9 rocket from Vandenberg Space Force Ba...
The mission's aim is to deliberately crash into Dimorphos to change the asteroid's motion in space, according to NASA. This collision will be recorded by LICIACube, or Light Italian Cubesat for Imaging of Asteroids, a companion cube satellite provided by the Italian Space Agency. It's the ...
The plan is to crash the spacecraft into Dimorphos when the asteroid system is at its closest to Earth—about 6.8 million miles away. (重达610千克的Dart航天器计划发射到目标Didymos小行星,这是一对无害的小行星,被称作Dimorphos的163米直径的小行星,围绕一个直径更大、被称为 Didymos(希腊语“...
If an asteroid were to threaten the safety of life on Earth in the future, this kinetic impactor mission may reveal how to deflect it, thus saving us all.
“DART will target Dimorphos, the much smaller ‘moonlet’ of a binary (two-body) asteroid system,”Kachele said. “Didymos, the primary body, safely orbits the sun and comes close enough to Earth such that scientists can observe it using ground-based telescopes. The dynamic of the binary...

Two things experts consider when judging any risk are:1)How likely the event is; and 2)How bad the consequences if the event occurs.Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years.Sounds pretty rare-but if one did fall,it would ...
DART will deliberately crash into Dimorphos to change the asteroid’s motion in space, according to NASA. This collision will be recorded by LICIACube, a companion CubeSat or cube satellite provided by the Italian Space Agency. The CubeSat will travel on DART and then be deployed from it prio...
